Hey trucks,
Was the truck scanned with just a code reader? Or scanner that can show datastream values? One possibility would be faulty/failed O2 sensors and a datastream "view" would pretty much diagnose it. I would recommend further testing (if possible) Let us know!

Thanks carundell. So my superchips scanner/programmer won't detect a bad o2 sensor or is that the sensors could be out of range . In that case im heading to the dealer right away and have them check it out .I thought it was something I could resolve but it looks like your right in having it checked out with a proper diagnostic tool. This is the first performance problem i have ever had with this truck and i thought it may have been easy to fix. Hopefully its as easy as putting a new sensor or sensor's in much cheaper than a fuel pump or new cat
thank you ..

On my ram hemi I have problems with the accuracy of the guage that tells you the mpg. It is very inconsistant and always wrong. If you haven't found a problem with your engine, you might try doing a manual check of the mpg's to make sure the gauge isn't faulty.

k so took the beast into the Dodge dealer last week they hooked it up to there scanner found no codes did find the downflow 02 sensor out of range and thermostat reading only 172 degrees .Said could have blocked cat and sensor reacting to it. So off i went to my garage tok the cat off and yes it was partilly blocked
installed a new aftermarket one also intalled a new 02 sensor and a new thermostat
the truck runs better now, gets better milage but still not like it was 2 months ago .I even checked all the recenty installed plugs and they looked good
I may intall the other 02 sensor on the upside of the cat to see if that makes any difference
and maybe a new IAT sensor ???

Trucks,
Wouldn't worry too much about the IAT(unless it codes), but a new upstream O2(s) may be a good PM move (due to excessive carbon contamination) also recommend reseting the fuel adaptives as the PCM may have "learned" some funky settings due to the clogged cat
